在高渗透率的可变发电下,确保足够的可调度资源供应是保持电力系统可靠性的关键。鉴于纯能源市场设计中的资金缺失问题,一系列司法管辖区已使用战略储备来采购对额外发电储备的投资。由于分布式资源和控制技术的进步,负荷的灵活性和异质性日益增加,战略储备采购需要能够反映能源消费者的不同偏好。为了应对这一挑战,本文开发了一种保险风险机制,用于采购战略储备,以适应未来的可变发电和灵活的需求。拟议的设计引入了一个中央保险计划与审慎的要求,使不同的消费者可靠性的偏好与财务目标的保险人的最后手段。我们说明了该计划的好处,(一)区分负荷的使用,使系统在极端稀缺的时候,更好的管理,(二)激励增量投资发电基础设施,是符合消费者的可靠性偏好和(iii)提高消费者的整体可靠性结果。
Securing an adequate supply of dispatchable resources is critical for keeping a power system reliable under high penetrations of variable generation. Strategic reserves have been used by a range of jurisdictions to procure investment in additional generation reserves given the missing money problem in energy only market designs. Given the growing flexibility and heterogeneity of load enabled by advancements in distributed resource and control technology, strategic reserve procurement needs to be able to reflect the different preferences of energy consumers. To address this challenge this paper develops an insurance risk mechanism for the procurement of strategic reserves that is adapted to a future with variable generation and flexible demand. The proposed design introduces a central insurance scheme with prudential requirements that align diverse consumer reliability preferences with the financial objectives of an insurer-of-last-resort. We illustrate the benefits of the scheme in (i) differentiating load by usage to enable better management of the system during times of extreme scarcity, (ii) incentivizing incremental investment in generation infrastructure that is aligned with consumer reliability preferences and (iii) improving overall reliability outcomes for consumers.
